RELATED APPLICATION

[0001] The present application is a continuation-in-part of U.S. patent application Ser. No. 09/576,924 filed on May 23, 2000, the entire disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

[0002] This invention relates to the field of food processing, and more particularly, to apparatus and methods for peeling vegetables and fruits.

BACKGROUND OF THE INVENTION

[0003] It is common in many food processing applications to require the peeling of the outer skin of fruits or vegetables. Potatoes, in particular, are very often so processed by passing the potatoes against a set of rotating abrasive rollers. Fruit may also be similarly processed. For example, U.S. Pat. No. 2,605,798 to Boswell discloses a citrus fruit peeler including a pair of abrading rollers and an auger screw which advances the citrus along the rollers.

[0004] Along these lines, U.S. Pat. No. 3,745,914 to Wallace discloses a single chamber fruit and vegetable peeler including a frame, a plurality of abrasive roller carried by the frame and arranged in an arcuate pattern, and a drive motor and gears coupled to the rollers. The abrasive rollers are provided in lengthwise segments to facilitate replacement of a damaged section without requiring replacement of an entire roller. Action of the rollers advances the fruit or vegetables from an intake to a discharge. A rinsing system is provided to wash material from the rollers. The vegetables or fruit are subjected to a tumbling action within the peeling chamber. The amount of peeling is controlled by a height of a gate at the discharge.

[0005] U.S. Pat. No. 4,519,305 to Vanosdall discloses a similar apparatus wherein an auger extends only partway into the chamber from the discharge. U.S. Pat. No. 5,858,429 also to Wallace discloses a similar apparatus which includes an auger at a feed hopper, and a rotatable tumbler including rotating paddles within the peeling chamber. This patent also discloses a vision analysis system to evaluate the degree of peeling and adjust the various parameters to provide a desired degree of peeling.

[0006] U.S. Pat. No. 4,237,782 to Bichel and U.S. Pat. No. 4,827,836 to Neidigh disclose peeling apparatus wherein the abrasive rollers are driven by individual hydraulic motors. U.S. Pat. No. 5,780,088 to Zittel discloses a peeler that includes individual electric motors to drive each roller. The rollers can be operated at different speeds or in different directions. An auger which extends through the peeling chamber, may also be controlled by an electric motor.

[0007] To increase capacity, a dual peeling or washing chamber apparatus was offered by Vanmark Corporation under the model designation Series 2800. The apparatus included two side-by-side chambers wherein the auger screws rotated in a same direction. Accordingly, the abrasive rollers extended around an arc further upward on a same side at the center of the apparatus. Unfortunately, this arrangement places a number of abrasive rollers in the interior of the peeling apparatus which makes maintenance more difficult for these interior rollers and associated portions. Such an arrangement also increases the needed width of the machine, thereby complicating its placement with other processing equipment.

[0008] Conventional peeling machines have also generally suffered from poor maintainability because of the mounting of rollers and respective motors. Accessing and replacing such components may be especially difficult since other processing equipment may be placed relatively close to the peeling machine. In addition, the bearings used in conventional machines may not provide a sufficient service life and/or permit high operating speeds of the rollers.

SUMMARY OF THE INVENTION

[0009] In view of the foregoing background, it is therefore an object of the present invention to provide a peeling apparatus and associated methods which permit more ready maintenance and/or which provide higher capacity.

[0010] These and other objects, features and advantages in accordance with one embodiment of the invention are provided by a peeling apparatus comprising a frame, a set of mounts including flange bearings and being removably connected to a first end of the frame adjacent at least one first roller opening, and a set of abrasive rollers being arranged to define a peeling chamber and having first ends rotatably supported by the flange bearings. The mounts permit the abrasive rollers to be installable or removable through the at least one first roller opening upon removal of the respective mounts from the frame. The peeling apparatus may also include a set of roller drive motors for respective abrasive rollers that are also carried by respective mounts. Accordingly, the motors and rollers can be readily removed and installed, such as for maintenance.

[0011] Each mount may have a trapezoidal shape, and the mounts may be arranged in side-by-side relation to define an arc. The peeling chamber may extend generally horizontally. The flange bearings used in the mounts may be more desirable than pillow block bearings which are often used in similar peeling apparatus.

[0012] A feeder may also be provided for feeding fruit or vegetables adjacent the set of abrasive rollers so that the first end defines an intake end. Accordingly, the mounts permit installation and removal of the abrasive rollers from the intake end.

[0013] In accordance with one advantageous feature, the number of abrasive rollers in the set thereof may be greater than eight. For a dual chamber peeling apparatus, the number of abrasive rollers may be greater than sixteen.

[0014] A second set of flange bearings may be carried by a second end of the frame for respective second ends of the abrasive rollers. Moreover, each of the second set of flange bearings may comprise a two-fastener flange bearing having a generally oval footprint. This permits each flange bearing of the second set of flange bearings to be canted at an angle and nested into an adjacent flange bearing. Since the second end is typically the discharge end, this relatively compact arrangement of flange bearings permits the fruit or vegetables to be readily discharged.

[0015] Another aspect of the invention relates to a high capacity peeling apparatus that includes dual peeling chambers and wherein feeders in the form of augers rotate in opposite directions. More particularly, the peeling apparatus may comprise a frame, and first and second peeling chambers carried by the frame in side-by-side relation. The first peeling chamber may include a first set of abrasive rollers and a first auger adjacent thereto, and the second peeling chamber may include a second set of abrasive rollers and a second auger adjacent thereto. The first and second augers preferably comprise respective helical flights oriented in opposite helical directions. The peeling apparatus may also include a drive for driving the first and second augers in opposite rotational directions.

[0016] The first set of abrasive rollers may be aligned along a first arc, and the second set of abrasive rollers may be aligned along a second arc being a mirror image of the first arc. To facilitate maintenance of the dual chamber embodiment, the first and second arcs preferably each extend higher along outsides of the peeling apparatus. In other words, the number of rollers along the inner portion of the apparatus is reduced in favor of more rollers along the more accessible outer portion.

[0017] Another aspect of the invention relates to cleaning. More particularly, the peeling apparatus may comprise a cleaning solution delivery system for contacting surfaces of the peeling chamber with a cleaning solution. This cleaning solution delivery system may be connected to a common cleaning solution delivery system that extends within the processing plant, and which is shared with other processing apparatus.

[0018] Additionally relating to cleaning, the peeling apparatus may include a cleaning solution collection system for collecting cleaning solution after contacting surfaces of the peeling chamber. This cleaning solution collection system may also be connected to a common cleaning solution collection system in the processing plant which is also shared with other processing apparatus.

[0019] One method aspect of the invention relates to a method for making a peeling apparatus. This method preferably comprises providing a frame, removably connecting a set of mounts to a first end of the frame adjacent at least one first roller opening with each mount comprising a flange bearing. The method may also include arranging a set of abrasive rollers to define a peeling chamber and having first ends rotatably supported by respective flange bearings of the mounts. Accordingly, the abrasive rollers are installable or removable through the at least one first roller opening upon removal of the respective mounts from the frame. The method may also include connecting a set of roller drive motors to respective abrasive rollers and that are also carried by respective mounts.

[0020] Another method aspect of the invention is also directed to making a peeling apparatus. The method may include providing a frame, and arranging a set of abrasive rollers to define a peeling chamber by rotatably supporting first ends of the abrasive rollers using a first set of flange bearings carried by the first end of the frame, and rotatably supporting second ends of the abrasive rollers using a second set of flange bearings carried by the second end of the frame.

[0021] Yet another method aspect of the invention is for peeling fruit or vegetables. The method preferably comprises providing first and second peeling chambers carried by a frame in side-by-side relation, with the first peeling chamber comprising a first set of abrasive rollers and a first auger adjacent thereto, and with the second peeling chamber comprising a second set of abrasive rollers and a second auger adjacent thereto. The first and second augers preferably comprise respective helical flights oriented in opposite helical directions. The method also preferably includes driving the first and second augers in opposite rotational directions to thereby advance the objects along the first and second sets of abrasive rollers respectively.

[0022] Still another method aspect of the invention relates to a method for processing fruit or vegetables using a plurality of processing apparatus and comprising at least one peeling apparatus. This method preferably comprises providing a common cleaning solution delivery system connected to the processing apparatus, and providing the peeling apparatus with a cleaning solution delivery system connected to the common cleaning solution delivery system. In addition, the method may include providing a common cleaning solution collection system connected to the processing apparatus, and providing the peeling apparatus with a cleaning solution collection system connected to the common cleaning solution collection system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The present invention will now be described more fully hereinafter with reference to the accompanying drawings in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

[0033] Referring initially to FIGS. 1-4 the peeling apparatus 20 in accordance with the present invention is now described. The peeling apparatus 20 may be part of an overall fruit or vegetable processing system 25 that may include other processing apparatus 21, 22 as schematically illustrated. In addition, these other processing apparatus 21, 22 may also be connected to a common plant cleaning solution system 23 including a cleaning solution supply and associated interconnecting piping. Similarly, these other processing apparatus 21, 22 may also be connected to a common plant cleaning solution collection system 24 including a drain, sump or collection vessel and interconnecting piping as will be appreciated by those skilled in the art.

[0034] The peeling apparatus 20 may include the lower collection pan 29 and the outlet port 31 in communication therewith which define the cleaning solution collection system for the peeling apparatus, and which may be coupled to the common plant cleaning solution collection system 24. Of course, the cleaning solution from the peeling apparatus 20 may also be recycled and used again for cleaning the peeler and/or any of the other processing apparatus 21, 22. Also the cleaning solution from the common plant cleaning solution delivery system 23 may be distributed or sprayed on interior portions of the peeling apparatus 20 using the schematically illustrated nozzles 35 (FIG. 4).

[0035] The peeling apparatus 25 illustratively includes two generally horizontally extending, side-by-side peeling chambers 26 a, 26 b, but many of the features and components thereof may also be used in a single peeling chamber apparatus, and/or in a peeling apparatus arranged at an angle other than horizontal as will be readily appreciated by those skilled in the art. The peeling apparatus 20 is also illustratively fed fruit or vegetables from one or more upstream devices, schematically illustrated in FIG. 1 by the fruit/vegetable supply 27. In addition, the peeling apparatus 20 also includes a controller 28 connected to the various motors and other equipment as will be described in greater detail below.

[0036] The peeling apparatus 20 may be used for many peeling operations to be performed typically on fruit or vegetables. For example, the peeling apparatus 20 may be used to extract oil from the peels of citrus fruit as disclosed in parent U.S. patent application Ser. No. 09/576,924 filed on May 23, 2000, the entire disclosure of which is incorporated herein by reference. Of course, the peeling apparatus 20 may be used for peeling potatoes, and other fruit and vegetables as will be appreciated by those skilled in the art.

[0037] The peeling apparatus 20 illustratively includes a frame 30 which carries the first and second peeling chambers 26 a, 26 b in side-by-side relation. The first peeling chamber 26 a includes a first set of abrasive rollers 32 a and a first auger 33 a adjacent thereto. Similarly, the second peeling chamber 26 comprises a second set of abrasive rollers 32 b and a second auger 33 b adjacent thereto. Each auger 33 a, 33 b has a respective electric drive motor 34 a, 34 b connected thereto. Of course, a discharge opening 37 a, 37 b is provided at the discharge end of each peeling chamber 26 a, 26 b as shown perhaps best in FIGS. 1 and 4. The discharge openings 37 are illustratively arcuate in shape and offset to the respective outer sides. A common intake opening 39 (FIG. 2) is provided at the intake end to receive the fruit or vegetables therein.

[0038] In accordance with one aspect of the peeling apparatus 20, the first and second augers 33 a, 33 b include respective helical flights oriented in opposite helical directions. The drive motors 34 a, 34 b drive the first and second augers 33 a, 33 b in opposite rotational directions. In other words, the drive motors 341, 34 b define a drive for the augers 33 a, 33 b. The fruit or vegetables in each peeling chamber 26 a, 26 b is advanced in parallel from the intake to the discharge end of the peeling apparatus 20.

[0039] The first set of abrasive rollers 32 a are aligned along a first arc, and the second set of abrasive rollers 32 b are aligned along a second arc being a mirror image of the first arc. Moreover, the first and second arcs each extend higher along outsides of the peeling apparatus 20. This may be accommodated since rotation of the augers 33 a, 33 b tends to cause the fruit to ride up toward the outside as will be appreciated by those skilled in the art. This arrangement of rollers provides a number of advantages, particularly in that more rollers are accessible from the exterior of the peeling apparatus 20, rather than being positioned on the less accessible interior as will be appreciated by those skilled in the art.

[0040] Another aspect of the peeling apparatus 20 is that the number of abrasive rollers 32 a, 32 b in each of the first and second sets may be greater than eight. In the illustrated embodiment, twelve rollers are provided in each set. A combined or total number of abrasive rollers 32 a, 32 b in both of the first and second sets is also preferably greater than sixteen. In the illustrated peeling apparatus 20 the total number of rollers is twenty-four. The larger number of rollers may provide a greater throughput in a smaller machine footprint. Accordingly, the peeling apparatus 20 may be installed or retrofitted into a relatively small space.

[0041] Referring now more particularly to FIG. 2 and additionally to FIG. 5, other advantageous features of the peeling apparatus 20 are now described. In particular, each peeling chamber 26 a, 26 b illustratively includes a set of motors 40 a, 40 b and associated mounts 41 a, 41 b for the abrasive rollers. These motors 40 a, 40 b and mounts 41 a, 41 b are illustratively carried by the intake end, accordingly, the fruit or vegetables can more readily pass out of the discharge openings unencumbered by the motors and mounts as will be appreciated by those skilled in the art.

[0042] For clarity of explanation, only a single motor 40 a, mount 41 a, and intake end of a roller 32 a will now be described, although those of skill in the art will appreciate that this configuration may be duplicated for all of the rollers in both peeling chambers 26 a, 26 b. More particularly, the frame 30 includes a roller opening 45 a adjacent the intake end. The roller opening 45 a may be an arcuately shaped slotted opening for the set of rollers as in the illustrated embodiment, or individual openings could be provided for each roller as will be appreciated by those skilled in the art. The mount 41 a is also connected to the intake end adjacent the roller opening 45 a, and this mount carries the intake end of the abrasive roller 32 a as well as the motor 40 a.

[0043] The mount 41 a permits the abrasive roller 32 a to be installable or removable through the roller opening 45 a upon removal of the mount 41 a from the frame 30. The mount 41 a also permits the roller drive motor 40 a to be separately removed, such as for service or replacement.

[0044] The abrasive roller 32 a illustratively comprises an elongate body portion 60 a having an abrasive outer surface as will be described in greater detail below, and an intake mounting stub 61 a and a discharge mounting stub 62 a (FIG. 7) permanently affixed to respective opposing ends of elongate body portion. Each mounting stub may include a body portion received within an open end of the elongate body portion 60 a, and may also include an integrally formed shaft extending outwardly therefrom. Other similar constructions are also possible.

[0045] The mounting stubs 61 a, 62 a are preferably permanently affixed to the ends of the elongate body portion 60 a to provide for higher rotational speeds with less vibration and resonance as will be appreciated by those skilled in the art. For example, in those embodiments where the elongate body portion 60 a of the abrasive roller 32 a comprises metal, such as steel or aluminum, the mounting stubs 61 a, 62 a may be permanently affixed by welding, although similar techniques are also contemplated by the present invention.

[0046] In the illustrated embodiment, the mount 41 a illustratively includes a base plate 46 a covering overlying the opening 45 a and secured to the frame 30. A flange bearing 47 a is carried by the base plate 46 a and rotatably supports the intake mounting stub 61 a at the end of the abrasive roller 32 a. The mount 41 a also illustratively includes the motor standoff 50 a also carried by the base plate 46 a and which is coaxial with the end of the mounting stub 61 a and output shaft 53 a of the motor 40 a. The output shaft 53 a of the motor 40 a is connected to the end of the mounting stub 61 a via a flexible coupling 51 a which may also permit higher rotational speeds for the abrasive roller 32 a by reducing vibration.

[0047] The schematically illustrated motor 40 a may include an electric or hydraulic actuator directly coupled to the output shaft 53 a, or an intervening gearbox may be provided to produce a desired rotational speed of the abrasive roller 32 a as will be appreciated by those skilled in the art. The motor 40 a is illustratively connected to a motor mounting plate 52 a which, in turn, is carried by the end of the motor standoff 50 a. Other equivalent mounting arrangements are also contemplated by the invention. In some alternate embodiments, the individual motors may be replaced by a common motor and associated drive train for driving the sets of rollers.

[0048] As perhaps best seen with reference to FIG. 2, the mounts 41 a, 41 b, and, more particularly, the base plates thereof, may have a trapezoidal shape. Accordingly, when the mounts 41 a, 41 b are arranged in side-by-side relation, the mounts define an arc.

[0049] Turning now additionally to FIGS. 6 and 7, another advantageous aspect of the peeling apparatus 20 is described. More particularly, respective sets of flange bearings 70 a, 70 b are provided at the discharge end of the peeling apparatus for each of the peeling chambers 26 a, 26 b. Each flange bearing 70 a is illustratively provided by a flange bearing having a generally oval footprint with first and second fastener openings adjacent opposing ends of the footprint and which, in turn, receive respective first and second fasteners 72 a to secure the flange bearing in place. The flange bearing 70 a of the mount 41 a rotatably supports the discharge mounting stub 62 a of the abrasive roller 32 a.

[0050] Moreover, as best seen in FIG. 7, each flange bearing 70 a with its generally oval footprint may be readily canted at an angle and nested into an adjacent flange bearing. In contrast, pillow block bearings, for example, may be difficult to accurately position and may take up additional space. Accordingly, the flange bearings 70 a, 70 b of the peeing apparatus 20 provide a very compact arrangement adjacent the discharge openings 37 a, 37 b so that the fruit or vegetables may be easily discharged therefrom.

[0051] Referring now additionally to FIGS. 8 and 9 other aspects relating to the abrasive roller 32 a of the peeling apparatus 20 are further described. The abrasive roller 32 a includes an elongate body portion 60 a, preferably in the form of an elongate tube to thereby reduce overall weight. The tubular shape may be readily and accurately formed by precision centerless grinding techniques as will be appreciated by those skilled in the art.

[0052] Mounting stubs 61 a, 62 a are preferably welded to opposing ends of the tubular elongate body portion 60 a as described above, and an abrasive surface is formed on the outer surface portion of the elongate body portion. The abrasive outer surface may be manufactured by pressing the outer roller surface against a shaping or die surface to form a pattern of knurls, similar to a #10TPI knurl. In other words, the knurls may be integrally formed into the surface of the elongate body portion 60 a.

[0053] A cross-section of one such knurl 75 a is shown in FIG. 9. The illustrated knurl 75 a may define a peak height of about 0.050 inches with a tolerance of about +0.00 and −0.020 inches. The abrasive roller 32 a may have a diameter of about 3.9 to 4.0 inches, although other sizes are also possible. Moreover, the knurl 75 a may have a leading edge portion 76 a that is steeper than the adjacent trailing edge portion 77 a. For example, the leading edge portion 76 a may define an angle α of about a thirty degrees from a line normal to the surface. Also, the trailing edge portion 77 a may define an angle β of about sixty degrees from a line normal to the surface. Other angles are also possible. The steeper angle of the leading edge portion 76 a may provide an extended wear life, and reduce the need for maintenance. In some embodiments, all of the knurls may have a same shape, although other embodiments may benefit from different shaped knurls.

[0054] To further provide increased wear resistance for the knurl 75 a a wear-resistant surface coating 80 a may be applied to cover the base metal of the elongate body portion 60 a. For example, the elongate body portion 60 a may comprise steel or aluminum, and the surface coating 80 a may comprise cobalt, chromium, tungsten, nickel, or alloys thereof. For example, Stellite® may be used as the coating 80 a and it is an alloy family containing cobalt, chromium, tungsten and other elements as will be readily appreciated by those skilled in the art.

[0055] In other embodiments, the base metal of the abrasive roller 32 a may not require a coating. For example, stainless steel may not require a protective coating. To reduce overall costs, in one preferred embodiment, a mild steel base metal may be combined with the protective coating 80 a as will be appreciated by those skilled in the art.

[0056] Turning now additionally to the schematic diagrams of FIGS. 10-11, various control aspects of the peeling apparatus 20 are now described. In particular, the peeling apparatus 20 includes a set of abrasive rollers 32 a arranged to define a peeling chamber 26 a, and roller drive motors 40 a as explained in detail above. A feeder 85 a is provided for controllably feeding fruit or vegetables adjacent the abrasive rollers. A sensor 86 a is associated with at least one roller drive motor 40 a for sensing a load thereon. For example, the sensor 86 a may be associated with one or more lower rollers to more accurately sense the load, although sensors may be provided for all of the motors as will be appreciated by those skilled in the art. The controller 28 is illustratively connected to the sensor 86 a and feeder 85 ab for controlling the feeder based upon the sensor. Accordingly, the feeder 85 a can be controlled based upon the sensed load on the abrasive roller 32 a.

[0057] For example, for typical operation, the controller 28 may increase the feed rate of the feeder 85 a based upon an increase in sensed load, and conversely decrease the feed rate based upon a decrease in sensed load. In some embodiments, the controller 28 may also control one more of the roller drive motors 40 a based upon the sensed load. This aspect of the peeling apparatus 20 provides a relatively straightforward, robust and cost effective approach to control important peeling parameters.

[0058] As understood with particular reference to FIG. 11, the feeder 85 b may comprise an input conveyor 90 a upstream of the set of abrasive rollers. In addition to or in place of the input conveyor 90 a, the feeder may include the auger 33 a adjacent the set of abrasive rollers. Also, the feeder 85 a may include at least one of an intake gate 91 a and a discharge gate 92 a, and with or without the input conveyor and/or auger. Those of skill in the art will recognize other feeder configurations that are controllable in accordance with this aspect of the peeling apparatus 20.

[0059] The sensor 86 a may comprise a torque sensor for sensing a torque delivered by the roller drive motor 40 a. In one class of embodiments, the roller drive motor 40 a may be a hydraulic motor 95 a, and the sensor 86 a may be a hydraulic pressure sensor 96 a. In one particularly advantageous class of embodiments, the roller drive motor 40 a may comprise a roller drive electric motor 94 a. Accordingly, for this class of embodiments, the torque sensor may thus comprise an electrical power sensor 97 a.

[0060] The controller 28 itself may include a processor 100 a and various input/output devices 101 a connected thereto. For example, the input/output devices 101 a may include an operator CRT display or other indicators, as well as a keyboard or other input devices as will be appreciated by those skilled in the art. Of course, the controller 28 may provide a range of from full automatic to full manual control as will also be appreciated by those skilled in the art. In addition, other features relating to the apparatus and method for peeling vegetables and fruit are disclosed in copending patent applications filed concurrently herewith and assigned to the assignee of the present invention and are entitled PEELING APPARATUS WITH ENHANCED ABRASIVE ROLLERS AND ASSOCIATED METHODS, attorney work docket number 12427/56042; and PEELING APPARATUS WITH ENHANCED ABRASIVE ROLLERS AND ASSOCIATED METHODS, attorney work docket number 12428/56043, the entire disclosures of which are incorporated herein in their entirety by reference.

[0061] Many modifications and other embodiments of the invention will come to the mind of one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Accordingly, it is understood that the invention is not to be limited to the embodiments disclosed, and that other modifications and embodiments are intended to be included within the spirit and scope of the appended claims.
